A questão dos Direitos Humanos e as suas violações continuam a passar despercebidas a nível mundial. Perante uma Paz negativa, é o dever da comunidade internacional interferir na construção de Paz em Estados dominados pela violência e fazer esforços na prevenção de conflitos. Os confrontos que se alastram em diferentes regiões da Somália, sob controlo de grupos rebeldes e a escalada de violência que levou a uma crise humanitária na Síria, com habitantes de ambos os países a terem de se deslocar e a refugiarem-se em países vizinhos por não se sentirem seguros no próprio país, são os estudos de caso escolhidos para analisar o que tem falhado na sua resolução. É também necessário realçar a emergência dos Estudos da Paz, presentes na ordem do dia da política mundial na mediação de conflitos, na gestão de crises e cooperação nas sociedades afetadas pela violência; Abstract: Human Rights in times of negative peace. Syria and Somalia as case studies The human rights subject and their violations continue unnoticed in a global level. Faced with a negative peace, it is the duty of the internacional community to assist in building peace in states where violence dominates and make efforts in preventing conflicts. The deadly confrontations that spread through diferentes regions in Somalia, under the control of rebels groups, and the escalation of violence that led to a humanitarian crisis in Syria, with the population of both countries moving around and taking shelters in neighbor countries because they don’t feel safe in their own, are the case studies chosen to analyze what has failed in their solution. It is also necessary to enhance the emergency of Peace Studies, which comes in the agenda of world politics in conflict mediation, in crisis management and cooperation in societies affected by violence.

In building, during the implementation process of major or even minor works, there is a considerable waste of plaster in the steps of coating, making it is a negative factor because of the loss of these processes constructive remains incorporated into buildings, as component, whose final dimensions are higher than those projected. Another negative factor is the disposal of waste gypsum in inappropriate places, thus contributing to the degradation of environmental quality, due to the leaching of this waste and may trigger the formation of sulfuric acid. Therefore, based on this picture, processing and reuse of waste coating, combined with the ceramics industry, which is a strong potential in the reuse of certain types of waste, promote mutual benefits. Thus the overall objective of this work is to conduct a search with scientific and technological aspects, to determine the effect of the incorporation of the residue of plaster for coating, from the building, the formulation of bodies for red ceramic. The residue of plaster coating was collected and characterized. They were also selected raw materials of two ceramic poles of the state of Rio Grande do Norte and formulations have been made with the intention of obtaining those with the best physical and mechanical properties, the residue was added the percentage of 5%, 10%, 15%, 20%, 25% and 30%, in the best formulation of ceramic industry 1 and, according the properties analyses, 5%, 10% and 15% as the best results of ceramic industry 2. The samples were sintered at temperatures of 850 ºC, 950 °C and 1050 °C, the heating rate of 5 ºC / min with isotherm of two hours. They were submitted to testing technology, such as lineal shrinkage, water absorption, apparent porosity, apparent density and bending resistence.

Abstrac: Today our society is constantly facing the need to adapt to a globalized world; ever changing life styles increase social differences; this circumstance leads to critical situations such as: extreme poverty, undernourishment, the need of a dignified life, shelter, clothing and labor; elements that become obstacles in building a culture of peace. Among the multiplicity of activities that contribute to peace; we will focus on highlighting the importance of sport as a bond of peace in which human beings find the ability to live and coexist peacefully. Considering including education for peace through sports, as it is a global medium that is not distinguished among cultures and which can be achieved with study, practice and internalization of values, lifestyles and education, would mean building a sense of enduring peace in our daily lives. En la actualidad nuestra sociedad se enfrenta constantemente a la necesidad de adaptación en un mundo globalizado; los cambios de ritmos de vida y el crecimiento de las diferencias sociales, son circunstancias que han generado situaciones críticas como la pobreza extrema, desnutrición, necesidad de una vida digna, vivienda, vestido y trabajo, elementos que se convierten en obstáculos en la construcción de una cultura de paz. Dentro de la multiplicidad de actividades que contribuyen a la paz, nos centraremos en destacar la relevancia del deporte como vínculo de paz en el que los seres humanos encuentran esa capacidad de vivir y convivir pacíficamente. Consideramos incluso la educación para la paz a través de los deportes, ya que son un medio global que no distingue entre culturas y que se puede lograr con el estudio, la práctica y la interiorización de valores, estilos de vida y educación, con lo cual estaríamos construyendo una idea de paz perdurable en nuestra vida diaria.

This research presents a study investigating the correlation between the environmental-physycal charcateristics of cities and the formation of its micro-climates. The study was conducted in the central area of Fortaleza characterized as a stable and consolidated area, where the city originated and currently faces serious problems in its urban dynamics. The points of measurements were determined by the elaboration and analysis of topography maps, height of buildings, land use, type of surface coating and vegetation, following the methodology of Katzschner (1997). A zoning map was then determined, according to common morphological characteristics of the 12 measurement points, which were based on a set of Romero s (2001) bioclimatic criteria. Air measurements, temperature, humidity, intensity and direction of winds were made in transect form in two different circuits in the study area, with six points of data collection in each area, in three different times: 6:00 am, 1:00pm and 7:00pm, during two periods of the year: August 2008 and March 2009. The results verified the influence of different environmental-physical types in the behavior of the climatic variables that were collected. A verticalização tão condenada em algumas situações se bem equilibrada e controlada pode reduzir as temperaturas do ar através do sombreamento dos espaços urbanos e possibilidade de maior permeabilidade a ventilação natural. The highest average air temperature and lower humidity were recorded at the point I at all times. This situation may have been in result of the high density, poor vegetation and extended paving of the ground. According to the results, it s clear the positive influence vegetation has on easing air temperature. Another indicator observed that areas with a greater variation in building heights tend to present decreased average air temperature. High rise structure, planned in accordance to urban air quality parameters, can reduce air temperatures by the shading of urban spaces and the possibility of greater penetration of natural ventilation

As most current studies, reinforced plastics have been, in recent years, a viable alternative in building structural elements of medium and large, since the lightness accompanied by high performance possible. The design of hybrid polymer composites (combination of different types of reinforcements) may enable structural applications thereof, facing the most severe service conditions. Within this class of composite materials, reinforced the underlying tissues hybrid high performance are taking space when your application requires high load bearing and high rigidity. The objective of this research work is to study the challenges in designing these fabrics bring these materials as to its mechanical characterization and fracture mechanisms involved. Some parameters associated with the process and / or form of hybridization stand out as influential factors in the final performance of the material such as the presence of anisotropy, so the fabric weave, the process of making the same, normative geometry of the specimens, among others. This sense, four laminates were developed based hybrid reinforcement fabrics involving AS4 carbon fiber, kevlar and glass 49-E as the matrix epoxy vinyl ester resin (DERAKANE 411-350). All laminates were formed each with four layers of reinforcements. Depending on the hybrid fabric, all the influencing factors mentioned above have been studied for laminates. All laminates were manufactured industrially used being the lamination process manual (hand-lay-up). All mechanical characterization and study of the mechanism of fracture (fracture mechanics) was developed for laminates subjected to uniaxial tensile test, bending in three and uniaxial compression. The analysis of fracture mechanisms were held involving the macroscopic, optical microscopy and scanning electron microscopy

Nowadays the acquisition of sustainable elements and concepts in construction has been increasingly discussed, improved and incorporated to buildings, since the sector directly interferes in the urban space and environment, representing environmental impact. In order to make a sustainable building (Green Building) it is vital to incorporate less damaging constructive practice, starting from the project until the operation of the enterprise, that means to consider an integrated process of conception, implementation, construction and operation. The more effective sustainable principles participation in architecture happens at the projecting step through minimal environment impact solutions. Among the issues varieties that goes with sustainability proposal of the buildings project, there were added to this work the elements that are directly attached to bioclimatic architecture, more specifically the climate variation, ventilation, lighting and sunlight, that directly affect the project conception. It is important to put in evidence that architecture role goes far beyond the simple activity of building spaces; it is the sequence of political, economic, social and cultural elements, having the users as the main apparatus to its materialization. Thereby this professional dissertation consists of an architecture draft for a professional and technological school in the Rio Grande do Norte State, this dissertation is based on the analysis of previous experience and the bioclimatic principles that implicate in building on hot and dry, hot and humid climates, and the use of strategic solutions that aim the optimization of natural light and ventilation

The need for efficient, sustainable, and planned utilization of resources is ever more critical. In the U.S. alone, buildings consume 34.8 Quadrillion (1015) BTU of energy annually at a cost of $1.4 Trillion. Of this energy 58% is utilized for heating and air conditioning. Several building energy analysis tools have been developed to assess energy demands and lifecycle energy costs in buildings. Such analyses are also essential for an efficient HVAC design that overcomes the pitfalls of an under/over-designed system. DOE-2 is among the most widely known full building energy analysis models. It also constitutes the simulation engine of other prominent software such as eQUEST, EnergyPro, PowerDOE. Therefore, it is essential that DOE-2 energy simulations be characterized by high accuracy. Infiltration is an uncontrolled process through which outside air leaks into a building. Studies have estimated infiltration to account for up to 50% of a building’s energy demand. This, considered alongside the annual cost of buildings energy consumption, reveals the costs of air infiltration. It also stresses the need that prominent building energy simulation engines accurately account for its impact. In this research the relative accuracy of current air infiltration calculation methods is evaluated against an intricate Multiphysics Hygrothermal CFD building envelope analysis. The full-scale CFD analysis is based on a meticulous representation of cracking in building envelopes and on real-life conditions. The research found that even the most advanced current infiltration methods, including in DOE-2, are at up to 96.13% relative error versus CFD analysis. An Enhanced Model for Combined Heat and Air Infiltration Simulation was developed. The model resulted in 91.6% improvement in relative accuracy over current models. It reduces error versus CFD analysis to less than 4.5% while requiring less than 1% of the time required for such a complex hygrothermal analysis. The algorithm used in our model was demonstrated to be easy to integrate into DOE-2 and other engines as a standalone method for evaluating infiltration heat loads. This will vastly increase the accuracy of such simulation engines while maintaining their speed and ease of use characteristics that make them very widely used in building design.

As the field of family business has grown immensely over the last couple of decades, a multitude of theories from different fields has been introduced. However, there are surprisingly few attempts to provide an overview of theories that may be of particular interest for the family business scholar. Thus, this introduction chapter gives a critical overview of theoretical perspectives, before taking a closer look at the use of theories in family business studies. Regarding the current state of the family business field, the authors argue for putting more effort in building theory from family business research as well as a stronger emphasis on ‘giving back’ to theories borrowed from other fields. Lastly, the chapter describes the development of the book and introduces the 13 chapters and their contributions.
